Datasheet VP5

Product catalog summary

Overview: The document provides technical specifications and operational details for the Series 5 measuring transducers, specifically models VP5.. and VPT5.., designed for temperature measurement using Pt100 and Pt1000 RTDs in a two-wire circuit.

Specifications:

Operating Voltage: 9 ... 32 V/DC, with reverse voltage protection and overvoltage tolerance.
Output Signals: Standardized voltage (0 ... 10 V/DC, 2 ... 10 V/DC) and current (0 ... 20 mA, 4 ... 20 mA) outputs, short-circuit-proof.
Input Signal: Pt100/Pt1000 RTD according to EN60751 Class B.
Temperature Ranges: Four ranges available (-30 ... +120 °C, 0 ... 120 °C, 0 ... 150 °C, 0 ... 200 °C).
Isolation: Galvanic isolation between sensor input and output signal.

Principle of operation: The transducer signal measured at the converter input is converted into a standardised output signal that is proportional to the input and lends itself to further customised processing, for instance, in a machine controller. General notes on Type VP5.., VPT5.. Description VP5.., VPT5.. Output signal The measuring transducers VP5.. and VPT5.. are designed to The output signal generated is a standardized voltage of evaluate the temperature with platinum Pt100 RTD (VP5..) or Pt1000 0 ... 10 V/DC or 2 ... 10 V/DC, respectively, a standardized current of RTD (VPT5..) according to EN60751 Class B in two-wire circuit. A 0 ... 20 mA or 4 ... 40 mA. The output signal follows the input signal platinum resistor has a positive temperature coefﬁcient which means that the resistance increases as the temperature rises. Access is provided to a trimming potentiometer to permit a line compensation to be applied for Pt100 RTD measuring transducers. The output signal can be used to supply additional devices, such as indicating instruments and limit-value switches. Point to be noted: the maximum driver capability of the output. Pt1000 RTDs do not require such compensation because, in principle, line resistance can be neglected. For better adaption to the required measuring task four measuring ranges are prepared: -30 ... +120 °C, 0 ... 120 °C, 0 ... 150 °C, 0 ... 200 °C. Monitoring for integrity and short circuit The devices are designed with sensor monitored for discontinuity and short circuit. In the event of any fault, the output signal setting is 22 mA or, respectively, 11.5 V. Electric isolation Sensor input and output signals are electrically isolated from Operating status display by LED the operating voltage.
